dominic earned $$1,500$ this year, and his employer withheld $$200$ of federal income tax from his salary. assuming that dominic is single, $30$ years old, and will have zero tax liability this year, he: is required to file a tax return, is not required to file a tax return but should file a return anyway, is required to file a tax return but should not because he owes no tax, is not required to file a tax returne and should not file a return, none fo the choices are correct?
